Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type.

In conventional ultrasounds, variations in soft tissue structure distort ultrasound wavefronts. They blur the image and can hence prove detrimental to medical diagnosis.

An international collaboration bringing together over 200 scientists from 13 countries has shown that the very high-energy gamma-ray emission from quasars, galaxies with a highly energetic nucleus, is not concentrated in the region close to their central black hole but in fact extends over several thousand light-years along jets of plasma.

Two exceptional strains of tuberculosis, isolated from East African patients with multi-resistant forms of the disease, have been discovered thanks to the use of a new molecular test, Deeplex-MycTB 1.
